英国生物与伦理论文 Britain through the legislation allows human cloning _ biological papers
Xinhua net London December 19, today in the British house of more than two-thirds of the overwhelming majority needed to pass a bill, allowing scientists to human cloning early embryos, and to extract stem cells for research. This undoubtedly throw out a collection of science, ethics, religion, law, and many other problems with a bomb, in English, arouse people's attention.
According to imagine, scientists will use somatic cloning technology, the use of early embryonic cells cloned, make it in the laboratory 6 to 7 days development, and then stop it continued to develop, extract embryonic stem cells. This kind of cells to differentiate into all kinds of cells have the ability of the human body, it may be possible to use the in vitro developed and provided cells genetic characteristics of patients exactly the same cell, tissue or organs, such as bone marrow, brain cells and myocardial even liver and kidney, etc, they can be used to treat leukemia, Parkinson's disease, heart disease, and diseases such as organ failure, this will also solve the organ transplant two big problems-rejection and donor organ shortage. Stem cell research huge medical value is self-evident, so it can in the us magazine, science selection of the 1999 world top ten scientific achievement was ranked first.
Support the legislation people think, the value of the study not only in its practical aspect, the in vitro culture of embryonic stem cells, observing it in different environment of growth, will help to understand a fertilized human eggs to how to accurately differentiation development of all kinds of the different cells, tissues and organs, and ultimately become a whole person. The individual life development of regulation, the origin of life and the consciousness of life science produce and classified as three big difficult problem, so through the observation of embryonic stem cells in vitro in the process of growth, make clear the above problems with special significance, it can make the human will no longer use religious superstitious eye to understand life, understand their own.
British some is opposed to the cloning of human early embryonic, mainly for two reasons. One is, even if only for a few days early human development of embryos is sacred life, only to get some useful cells and creating a life to destroy it, is an ethics. The second reason is that human cloning early embryonic become legal behavior, means that the relaxation of the control of human cloning, prompting the emergence of human cloning.
But support the research scientist and government people are of the opinion that a only by come of a cell of early embryonic can be a "people", the nerve tissue is far from development out, no feeling more no consciousness, does not have the fundamental ethical issues. And, early embryo cloning human individual complete with cloning and do not have direct connection, if for strict control, and can completely avoid the appearance of human cloning.
In recent years, along with the development of science and technology especially biological technology, advocated a mood grow in Britain, main show is against human cloning early embryonic, against genetically modified food, opposed to using animals to conduct medical experiments. November this year, / British prime minister Tony Blair in Europe biological science addressing a meeting said, must be alert to the antiscience trend, the British government will be to controversial scientific research to strict management, but also can resist the normal pressure security research, keep Britain biological technology in Europe's leading position. British house of representatives passed the cloning of human embryos early on the proposal, once again, clearly conveys a powerful signal: ethical dispute to dispute, the British government and legislative institutions will not so in science and technology and economy of its significant interests of the restraint on, but to make full use of the new technology for their own development services, and the strict management measures to prevent its negative influence.
Some people point out, the human ethics is variable, in a period of the ethics of totally unreasonable behavior, with the thought and the progress of science and technology, may become very natural. Blood transfusion technology just developed, someone to attack, so far in some western countries still people who refuse to accept a blood transfusion treatment. But no one can deny, blood transfusions technology saved hundreds of thousands of lives. The first test tube baby Louise brown was born in Britain in 1978, also has caused the great ethics controversy, and now the world test tube babies are already more than 300000 cases. Some important scientific and technological progress, born in someone who curse, some fear, but this one is accepted by the human progress, depend on whether it is beneficial to human welfare, and is not whether or not at that time is the ethics and legal terms. Keep on researching the objective law of the things, use of science and technology and for human create a better life, this is the human's pursuit of truth. (out)
